COTTAGE GROVE RESERVOIR, WILLAMETTE RIVER BASIN, OREG. Location. On the Coast Fork of Willamette River, 29 miles from the mouth. The Coast Fork rises in Douglas County, Oreg., on the western slope of the Cascade Range, and the northern slope of the Calapooya Range, flows north for 49 miles, and unites with the Middle Fork to form the main Willamette River. The drainage area tributary to this reservoir is 104 square miles. Existing project. The plan of improvement provides for construction of an earth-fill dam 1,650 feet long at the crest, rising 95 feet above the stream bed, with a reservoir providing for storage of 30,000 acre-feet. The spillway, 264 feet long, is a concrete, gravity, overflow type forming the right abutment. Outlet works, consisting of three gate-controlled conduits, will pass through the spillway section. The reservoir will be operated as a unit of the coordinated reservoir system to protect the Willamette River Valley and to increase low water flows for navigation. The existing project was selected for construction under the general authorization for the Willamette River Basin contained in the Flood Control Act approved June 28, 1938. The estimate of cost for new work, revised in 1944, is $2,251,000. Local cooperation.-Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year-New work.-Construction of a shelter on the concrete section of the dam and the installation of a domestic water supply system were initiated. Maintenance.-Operation of regulating gates, maintenance of structures and grounds and the burning of debris left on the reservoir shore were continued during the year. Controlled discharge during the low-water season was maintained in amounts sufficient to satisfy downstream water rights. Fall depletion of storage was initiated on September 12, 1944, and was timed to give maximum benefit to navigation requirements. The maximum controlled discharge, 2,000 cubic feet per second was reached on October 15 and the minimum pool elevation was obtained on November 11. The reservoir water surface was maintained at or very near the minimum pool level during the entire flood-control period. Storage of water was initiated on February 1, 1945, according to schedule. Maximum reservoir inflow for the season amounted to 2,200 cubic feet per second. The corresponding discharge, 1,200 cubic feet per second was well within the downstream channel capacity. Filling of the reservoir was completed on May 4, 1945. Full control of the reservoir and all water passing through it was maintained through the year. Total costs during the fiscal year were $18,415.54, of which $1,818.37 was for new work and $16,597.17 for maintenance. Expenditures were $18,134.89. Condition at end of fiscal year.-Construction of the dam and appurtenant work was completed in 1942 and the dam has been in continuous operations since that time. The project as a whole has been completed except for minor items which have been deferred for the duration of the war. Total costs have been $2,288,936.28, of which $2,231,868.85 was for new work and $57,067.43 for maintenance. Expenditures have been $2,289,117.47.

DORENA RESERVOIR, WILLAMETTE RIVER BASIN, OREG. Location.-On Row River, Oreg., 7 miles from the mouth. Row River rises in Lane County on the western slope of the Cascade Range, flows northwest for 19 miles, and enters the Coast Fork of Willamette River 1912 miles above the mouth. The drainage area tributary to this reservoir is 265 square miles. Existing project.-The plan of improvement provides for construction of an earth-fill dam 4,650 feet long at the crest, rising 145 feet above the stream bed, with a reservoir providing a usable storage at normal pool level of 70,000 acre-feet. The spillway will be an uncontrolled ogee and chute around the right abutment of the main dam. The outlet works, consisting of a tunnel controlled by a cylinder gate, will discharge into the chute section of the spillway. The reservoir, controlling practically the entire drainage area of Row River, will be operated as a unit of the coordinated reservoir system to protect the Willamette River Valley and to increase low-water flows for navigation, and for other purposes. The existing project was selected for construction under the general authorization for the Willamette River Basin contained in the Flood Control Act approved June 28, 1938. The estimate of cost for new work, revised in 1940, is $4,276,000. Local cooperation.-Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-Studies to determine better alignment for the earth dam and hydraulic model studies of a curved spillway crest were completed during the fiscal year. The project plan was revised to incorporate changes due to realignment of the dam axis and other changes. Total costs for the fiscal year were $73,369.09, all for new work, Expenditures were $76,012.59. Condition at end of fiscal year.-No construction has been done on the dam and appurtenant works, but plans and specifications for post war construction of the project are practically complete. Clearing of the reservoir site is 17 percent and the acquisition of lands and easements approximately 83 percent complete. Highway and railroad relocations are respectively 60 and 70 percent complete. Total costs have been $1,247,746.30 all for new work. Expenditures have been $1,244,996.46. Proposed operations.-The funds unexpended June 30, 1945, amounting to $12,803.54 will be applied as follows: New work: Accounts payable Completion of model tests__ Completion of contract plans and specifications_ Total $2,749.84 1,500.00 2,663. 70 5, 890.00 12, 803. 54 The additional sum of $3,018,200 can be profitably expended during the fiscal years 1946 and 1947 ($1,000,000 of this total in 1946) as follows: |
